and bricksj but usuali).Y as tiles, and its objee-t is to produce a building element that will have maximum crushing strength for its weight and which will retain its sliepe while being made. l

This invention consists in a building ele-- ment or tile having end walls and parallel longitudinal side and partition Walls sepa "of arches.

rated by air spaces, these longitudinal walls being I'einl'oree lby means of vertical ribs a'nd`held parallel -to eaeh other b v means it further consistsin forming flanges along the inner edges ot these walls along both the top and bottom of the tiles in order to furnish increased bearing areas. ir desired.

ln the accompanying drawingy Figure 1 is a plan of a tile embodying thefinvention set forth herein. llig. Q is a section on the line Q--Q of Fig. l. llig. 53 is a section on the line. of Fig. l. Fig. 4 is a seetion on the line l-l of Fig. 5 ot a modified form of tile. Fig. 5 is a section on the line of liig. 4. Fig. (l is a side elevation of both forms of the.t`le.

Similar reference marin-ters refer to like parts throughout the several views.

Tiles and other forms of blocks are Vformed with air spaces in order to save material and also because building elements 'thus formed are better non-conductors` of heat and cold than solid blocks.. The walls in such tiles are placed verticallyl in the building in order that these air spaces may be continuons and in order that load niay be efeotnally carried. When the walls of tiles oi plastic material are made thin, they are liable to Warp while hardening and the edges oit these walls .sometimes settle undesired distances into' the mortar used to seonre the tiles together,ll because of the narrowness of the bearing 'edge of these Walls of the tiles.

Tlie-sifresent invention is incorporated in two forms of tiles, one shown in Figs. l, 5 and (3 may be made on ya machine having straight cores and the other shown in Figs. 2 and 3 on a machine having:r collapsible cores. ln both these t'orms ot' tiles l and 2. the outer faces ot' the walls are prefer-A ably formed with vertical longitudinally parallel grooves -l and l, each being cut in at an oblique angle to the face of 'the tile and adjacent grooves 3 and -l are preferably cut at opposite angles. These grooves are of great advantage in holding mortar between the ends of adjacent tiles and stucco and plaster that may be applied thereto after the building wall is completed.

lt has also been found that by forming the longitudinal walls of the tiles with the ribs (i and i' and connecting these ribs by means of arches S and l) respectively. the walls l() and ll and ill and ll are not S0 liable to bnlgeand warp during the. -Inanir t'ai'ture oli the tiles and that their load-sus taining power is greatly increased. he number of these transverse arches may be varied as desired. The end walls 12 and 17 connect'tlie longitudinal walls of these two i tiles respectively'.

i When tiles ot' this general type are laid up in a wall. the weight thereof and the load carried thereby is liable to torce the bottoms of the vertical walls of the tiles into the mortar and thereby' destroy the alinement ot' the tiles in the walls. To prevent this. interior flanges l5 are formed at the lower edges of these walls. the bottom 'faces otx the flanges being in the same plane as the louer edges o1 the walls of the tiles. n order to stiften the tiles and to supply a goodly area to support the mortar, the flanges 1G may be formed along the upper edges of the walls of the tiles` these flanges being in the plane of such upper edges.

ily forming the tiles with the upper .flanges 16, means are provided whereby Elliy GO said A,
